Order an AI Plushie from the Genesis Collection early-bird tier via x402 payment on Base Sepolia.
What it does
This x402 endpoint on staging.plush.fun lets an AI agent create an order for a physical AI Plushie from the Genesis Collection at the early-bird price of $159 USDC. Payment is settled on-chain via USDC on Base Sepolia (testnet). The endpoint accepts a POST request with a JSON body specifying collectionId, tier, quantity, and unitPriceCents, and returns an orderId, totalCents, and order status.
The Genesis Collection is described as the first AI Plushie collection featuring AI-generated personality characters. It is limited to 4,000 units total, with shipping starting once 2,000 units are sold (projected Q1–Q2 2026). If the minimum production goal is not reached, buyers are automatically refunded. Free worldwide shipping is included once the threshold is met. As of the crawl, 160 of 4,000 boxes had been sold.
Important: this endpoint is on a **staging** environment (staging.plush.fun) and settles on **Base Sepolia** (a testnet), so it is not a production/mainnet purchase. The x402 challenge requires 159,000,000 base units of USDC (6 decimals), which equals $159.00. No OpenAPI spec or dedicated API documentation was found; the schema is derived entirely from the x402 outputSchema in the 402 challenge.

Quality
The x402 challenge is live and includes an outputSchema with input/output field definitions, giving a reasonable picture of the API contract. However, this is a staging/testnet endpoint with no OpenAPI spec, no dedicated API docs, and no example responses beyond what the schema implies. The crawl pages mostly returned 404-style content except the homepage. Price and schema are clear but documentation is thin.
Warnings
- —This is a STAGING environment on Base Sepolia (testnet), not a production mainnet endpoint.
- —No OpenAPI specification or dedicated API documentation found.
- —robots.txt explicitly disallows /api/ paths, suggesting this endpoint may not be intended for public crawling.
- —The response schema (orderId, totalCents, status) is inferred from the x402 outputSchema and has not been verified with a real response.
- —Physical goods fulfillment depends on reaching 2,000 units sold; refund policy applies if goal is not met.
